I don't know as much as I should about moose either, but I wouldn't use the Snowies or Bighorns as a litmus test for understanding moose. Those areas have a high density of moose compared to just about anywhere.
I've been fortunate to spend most of my life working in the woods in some sort of moose habitat in ID, MT, WY, UT and CO...and what I've learned is it all isn't created equal. What applies in one state, or one region of the State, doesn't mean much. That is to say, animals like elk and mule deer are much more predictable from State to State, region to region...not that tough to figure out. Moose? Not so much in my experience.
To give examples, and again I'm not a moose expert, only been on 7 successful shiras hunts over the years.
In Montana I drew a hunt that started Nov 15 and went through Dec 15. I "scouted" the area in September and the moose were in the willows/red osier dogwood along major creeks and small rivers. Saw lots of moose. When my hunt started, I couldn't find a moose low at all where I'd seen them in September, no tracks, no sign, no nothing. With nothing to lose, I started to hunt higher and when I got into the sub-alpine and lodgepole dominated habitats, I started seeing tracks and sign right away. Those moose had pulled UP into smaller drainages at higher elevations, I would guess after the rut. They were using small openings and edge habitat on small open areas and in small tributaries. That's NOT what I would have expected...I thought with snow and cold up high, they would be down in the same bottoms I saw them in, in September.
This provided quite the challenge as I wasn't really prepared to be driving/hiking/packing moose in a couple/three feet of snow. I ended up killing this bull in a very small meadow I located in the middle of a mixed conifer stand by following tracks. There were 5 moose in the opening when I killed this one:
My younger brother drew the same area, but his hunt started September 15...knowing what I saw when I drew many years prior, I told him to look in the lower elevation stuff until after the rut. He found this bull probably 1500-2000 feet lower in elevation and about 6 miles from where I killed my bull.
My Dad drew 2 cow permits in the area just to the South and it was the same story...in November, the moose were using small openings in dense conifer stands at higher elevation than where they were in September/October.
Another friend drew and again we found moose in the very highest portions of bigger tributaries or in small openings in the conifers, not exactly intuitively obvious when they could have been in much lower willow/red osier dogwood bottoms.
